Description

Adjustable glasses

The present invention relates to a pair of glasses, and more particularly to an adjustable number of glasses.

Referring to FIG. 1 , the general-purpose glasses on the market include a frame body 6 for the user to hang, and two lenses 7 detachably disposed on the frame body 6 and having a predetermined curvature, and the user borrows the glasses. The frame body 6 is hung on the face, and the curvature of the lenses 7 is used to correct the degree of myopia of the eye to clearly see the surrounding things.

Current myopia glasses for myopia patients, because the curvature of the lens 7 is fixed, it can not meet, for example, the need for higher curvature when driving to clearly identify distant scenes, and the need for low-curvature reading for close reading. The need for the situation.

Similarly, the same is true for presbyopic glasses that are needed for presbyopic patients; but it is gratifying that, because the condition of presbyopia patients is more complicated than that of myopia, in order to help the vision correction of presbyopic patients, there are, for example, lenses on the market. The part with different curvature, the upper part is for the user to watch the far side, the lower part is for the user to watch the near-two-light reading glasses, or the lens is divided into upper, middle and lower three-light reading glasses with different curvatures. And the lens is divided into a plurality of asymptotic multifocal reading glasses with different curvature parts to assist the presbyopic patients to identify and see the surrounding things.

However, the dual-light reading glasses technology and the three-light reading glasses are used in that the curvature of each lens is divided into two parts or three parts, so when the user switches from near to far, the user must hold the glasses to adjust. The line of sight corresponds to the region of different curvature of the lens, and it is inconvenient to use, and it is easy to cause dizziness due to the curvature change of each part of the lens, and the phenomenon that the field of view is more easily blurred at different distances.

As for the progressively multi-focus reading glasses, because of the gradual progressive diopter, the user can obtain a clear vision from the distance to the near side through the lens, but the lens is limited by the small focal distance. Factor, so when the user looks at a certain focus point for a long time, it is easy to cause eye fatigue, and it is not suitable for long-term wear.

In summary, current myopia glasses, or various types of reading glasses, are still insufficient to meet the needs of use and need to be improved.

Accordingly, it is an object of the present invention to provide an adjustable number of glasses.

Therefore, the adjustable eyeglasses of the present invention comprise a frame body for the user to hang, at least one lens unit disposed on the frame body and including the plurality of lenses, and an adjustment disposed on the frame body and connected to the lens unit. unit.

The frame body defines a base line that is parallel to the user's eyes.

At least one of the lenses has a plurality of degrees, and the curvature of each of the degrees varies along a direction perpendicular to the baseline.

The adjustment unit interlocks the lenses relative to each other in a direction perpendicular to the base line.

The effect of the invention is that by adjusting the adjusting unit, the lenses in the at least one lens unit are relatively displaced relative to each other in a direction perpendicular to the base line, thereby achieving the degree of adjustment, so that the user can select different degrees of use for different needs.
